[Cataract surgery in diabetic patients]. / Chirurgia cataractei la pacientii diabetici.

PURPOSE: Analysis of functional results, per- and postoperative complications after cataract surgery in diabetic patients. MATERIAL AND METHOD: Retrospective study including 100 non-diabetic patients and 50 patients with type II diabetes, with extracapsular extraction and IOL implantation in the postoperator chamber followed for 10.3-7.3 months postoperative complications. RESULTS: Postoperative visual acuity was lower in diabetic patients (0.317 +/- 0.24) versus non-diabetic patients (0.634 +/- 0.30); postoperative visual acuity was lower in diabetic patients without retinopathy (0.437 +/- 0.26) versus diabetic patients with non-proliferative retinopathy (0.348 +/- 0.26) or diabetic proliferative retinopathy (0.116 +/- 0.11); the incidence of per- and postoperative complications (early and late) is higher in diabetic patients compared with the control group. CONCLUSIONS: Cataract surgery in diabetic patients is followed by higher rate of per- and postoperative complications. The postoperative functional result is dependent, in principal, on the retinal status of the diabetic patient and, secondary, on the per- and postoperative complications.

[Primary trabeculectomy in the surgery of primary open angle glaucoma]. / Trabeculectomia tratament primar al glaucomului primitiv cu unghi deschis.

OBJECTIVE: Comparative analysis of the results of trabeculectomy in the surgery of primary open angle glaucoma (POAG) as the primary therapeutical approach and after the medical treatment failure. MATERIALS AND METHOD: Retrospective study including two therapeutical groups: A (59 patients) with primary trabeculectomy; and B (60 patients) with trabeculectomy following a medical treatment failure; mean follow-up period was 3 years and 5 months. RESULTS: Postoperative drop in intraocular pressure was similar in the two groups; there is no statistical significant difference between the two groups regarding stationary disease (76.27% in group A, versus 73.33% in group B), regressive disease (6.8% versus 6.7% respectively) and progressive disease (18.6% in group A, versus 21.6% in group B). At an intraocular pressure < or = 21 mmHg 13.6% of glaucoma cases do progress. The rate of peroperative and postoperative complications is similar in the two groups. CONCLUSIONS: The prior medical treatment of glaucoma doesn't affect the evolution of operated POAG. Primary trabeculectomy is indicated for non-compliant patients and for patients in whom administration of combined medical treatment for short time periods doesn't lower the intraocular pressure at safe levels. Surgical treatment has the advantage of an important and constant lowering of the intraocular pressure which is an absolute requirement for an efficient control of advanced glaucoma.
